• User interface is present on the top of the SG-BWS-T4 for signalling and configuration.
• Two units made of 8 dip-switches are present on the top of the SG-BWS-T4-MT model. These switches activate/deactivate and configure additional functions integrated in the device.
• Signalling interface and dip-switches are protected from non-authorized access by transparent lids that can be opened using a specific tool.
The EDM and MAN/AUTO Restart functions integrated in SG-BWS-T4 model can be selected through specific control unit lines (refer “CONNECTION” section of the present document).

INDICATORS
An user interface is present for viewing warnings and setup is present on the top of both SG-BWS-T4 and SG-BWS-T4-MT control unitsBesides the 7-segment display (for diagnostics purposes), the warning components include 3 LEDs:

NORMAL No danger: safety outputs closed
SAFE Danger or fault: safety outputs open
The 7-segment display shows detailed information on control unit current status

MUTING WARNING DEVICES
To use the Muting function it is also required to connect the external Muting warning (lamp) since control unit would lock out if it is missing. One lamp shall be used per channel. If device is preset for use of just one channel, both warning devices are associated to it: in this way, failure of one of the lamps would not lock out system operation.SG-BWS-T4-MT allows installation of both incandescent lamps and LEDs. For the latter case, polarity shall be carefully complied with, as indicated aside.
Note: the Muting lamp is not supplied with the device. Please refer to “Accessory selection and order information table.”
Thanks to its two separate muting channels, SG-BWS-T4-MT can accept the muting request output by sensors without interrupting the safety function on light curtain or safety sensors of both channels.

SG-BWS-T4 CONNECTIONS
NOTE : As SG-BWS-T4 has OSSD Safety outputs in order to have relay outputs, the device must have EDM function connected to the CS-ME EDM relay box as represented below:
